Application filed March 329, 1916. Serial No. 87,640.

To all whom it may concern:

Be it known that I, HENRYH. SANFORD, a citizen of the United States of America, reslding at Mansfield, in the county of Richland and State of Ohio, have invented certam new and useful Improvements in Stoves, of which the following is a specification.

The invention relates to an improved stove constructed with a view to providing means in the same stove body, for the burnmg of a desired.

In natural gas regions, there is constant llability to low "pressure periods, during Which the gas is not properly available as a fuel, and furthermore, in some of such reglons the natural pressure is gradually becoming less. It is therefore of importance that, particularly for such regions, means should be devised which will adapt a stove for the use of gaseous fuel, when such is properly available, and yet permit the stove to be readily used for solid fuel, upon failure of the gas supply or the exhaustion of i the gas.

The present. stove is designed particularly with a View to permitting the use of gaseous fuel or solid fuel at the will of the user, the conversion of the stove from one type to the other involving merely the removal of the burners for the gaseous fuel.

In the stove structure to which the present invention is directed, there are certain de- $5 tails which are of importance in a com bined type of stove, particularly the arrangement of the smoke flues; the means for conducting the products of combustion all around the oven; means for securely closing 40 all of those openings in the stove arranged to permit the insertion or attachment of gas burners when it is desired to convert the stove for the burning of solid fuel; and means for directing the fumes of the cookat ing to pass directly into the smoke flue when gaseous fuel is being used, and check the fire when solid fuel is used.

The invention in the preferred form of details will be described in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a view in elevation of the improved stove; a Fig. 2 is a side elevatlon of the same;

gaseous or solid fuel as may be" Fig. 3 is a broken plan of the same;

Fig. 4 is a broken sectional view illustrating particularly the closure for the opening above the oven;

Fig. 5 is a longitudinal section through the body of the stove;

Fig. 6 is a sectional view on line 66 of Fig. 5.

The stove of the present improvement is here shown as what may be termed the conventional form, although it is to be understood that the details of structure are in no wise limited to this particular form. The stove is preferably constructed to provide the usual body 1, in the form of a rectangular casing of appropriate size having the overhanging top 2, from which at the rear rises the usual back 3, the stove as an entirety being supported upon legs 4-, or the like, the various parts of the stove just described being constructed as preferably in .the form illustrated in the drawings, and

of course of wrought metal. The interior of the stove body is divided by a transversely arranged partition 5 which rises from the bottom of the stove, and extends for the full width thereof, terminating short of the top, however, as will be seen in Fig. 5. The partition divides the stove into spaces of unequal length, the space of shorter length being adapted to receive in the relatively upper portion thereof, any ap propriate form of solid fuel receiver 6, such as a fire-pot, grate, or the like, the said fuel receiver having what may be termed its inner wall terminating on a line with the top of the partition, so that the fuel space is in open communication with the space beyond the partition 5. Arranged within the remaining space of the body is an oven 7 of rectangular-formation having its respective front and rear wall coincident with the similar walls ofthe body and its side wallsv close the flue 11 throughout the longitudinal extent of the baffle plate. The bafie plate thus interposes an opposition in the flue 11 to the direct flow of the heated products, compelling said products to pass around the baffle plate before reaching the vertical portion of the flue 5 next the fuel receiving space.

The back 3 of the stove, throughout that vertical half of the stove proper which in cludes the fuel receiving space, is extended for the full normal height of such back, and provided at the upper end with what may be termeda canopy 14 and below the same with a shelf 15, the usual side walls 16 being provided. The remaining half of the back extends for a short distance above the stove body as at 17 and the remaining distance is taken up by a gas oven 18, the detail structure of which is unimportant with respect to the present invention, it being understood that it is provided with the usual broiling and baking receptacles 19 and 20, fuel pipe 21, and such accessories as are necessary to complete the structure.

-The disposition of the oven with respect to the remaining portion of the back is an important detail of the present invention, as it will be obvious that the oven supported largely from brackets 22 rising from the stove body is arranged so that it projects rearwardly beyond the back proper, so that there is thus provided at the juncture of the back and projecting portion of the oven, angularly related sections in'which the smoke pipe 23 is snugly received and secured. The oven top constitutes in effect an extension of the canopy so that by this arrangement there is provided a means for rigidly securing the smoke pipe in place, while avoiding any obstruction to thetop portion of the stove. The smoke pipe 23 terminates at its lower end in what may be termed a flue box 24, of increased sectional dimension as compared with the similar dimension of the smoke pipe, and so located as to include or register with the flues ,5 and 11 about the oven, both above and below the extension 12 of the top wall 9 of the oven. The flue 5 below the cross partition 12 communicates directly with the flue box through an opening 25 in the rear wall of the stove body, that portion of the flue above the top wall of the oven also communicating with the flue box through an opening 26. This opening 26 is comparatively elongated, and controlled through a damper plate 27, fixed upon arod 28, pivotally mounted on the inner side of the rear wall of the body as at 29, and projecting beyond the side wall of the body in the form of a handle 30 for convenient operation. The forward wall of the stove is provided with the usual door closed openings 31 and 32 providing access respectively to the oven and to the space in the fuel naa'ncve chamber below the receiver 6, for draft purposes, removal of the ashes and the like.

The stove so far described is particularly designed for use with solid fuel, although its construction is such as to render it particularly designed for such modifications as will permit it to be readily converted into a gaseous fuel'stove "when desired. To this end it is to be understood that means must be provided for the introduction of the usual gas burners when gaseous fuel is to be used, and to provide means for closing the stove body upon the withdrawal of the said gas burners in order that the stove might be adapted for solid fuel.

In providing for the use of gaseous fuel the forward wall of the stove above the upper limits of the oven 7 is formed with an opening 33, which registers with the fine 11 and is of somewhat less length than the length of the stove on one side of the partition 5. The opening 33 is provided with a door or closure 34, hinged at 35 to the front wall of the stove and adapted-to pivot upwardly when desired to completely close the opening 33. In its lowered or opened position, the closure 34 rests upon the top 9' of the oven, as clearly shown in Fig. 1, and it is adapted to be maintained in its closed position when desired by a turn butt0n36 pivotally mounted on the wall of the stove adj acent the closure and operable from the outer side of the stove The forward wall of the stove on the opposite side of the partition 5 in longitudinal alinement with the opening 33 is formed with an opening 37, for the reception of a burner. this opening when not in use to receive the gaseous burner, being designed to be closed by a door or closure 38 pivotally mounted on the stove wall and operable in an obvious manner as will be plain from Fig. 1 of the drawings. The above top 2 is provided with the usual openings 39 adapted to be closed by the lids 4:0 and these openings are preferably arranged so that upon the introduction of the gas fuel burners 41 the said burners will register with the openings so that in the use of the stove for burning gas the removal of the lids provides the ordinary gas burners permitting direct application of the heat tothe utensil. The burners 41 are mounted in any manner to properly support the burners interiorly of the stove, it being understood that the connected parts include the control valves, air admission ports, and the like, as is common in burners of this type. I

, The back 3 immediately beneath the canopy 14 is formed with an opening 43 which communicates directly with the smoke flue- 23, any suitable form of damper or cut-0d 4:4 controlling this opening. The opening is arrangedto permit the fumes to escape when gaseous'fuel is being used and to operate as a check damper in the use of solid fuel.

naa'zgeve In the use of the stove for gaseous fuel, the closures 34 and 38 are turned to expose the openings and the gas burners in completed form are inserted in place. In this arrangement the damper 27 is turned to its closed position and the stove used as an ordinary gas stove. In the use of solid fuel the closures 34 and 38 are operated to close the opening after the removal of the burners and connected parts, the fuel is introduced into the grate or receiver 6, and the damper 27 turned down to permit the products of combustion to flow directly into the smoke flue, until a proper burning of the fuel is attained, whereupon the damper is closed and the products of combustion compelled to reach the smoke flue through a complete circulation about the oven through the flues 11, 11, 11 and 5'. The baflle'plate 13 forces a lateral movement of the products of combustion in a direction opposite the smoke flue to insure a moreefl'ective heating result from such products. During the use of the stove as a gas stove, the damper 44 may be opened to permit the fumes from the cooking and the like to escape directly into the smoke flue, and the said damper is also effective in providing a means for checking the fire by interfering with the direct draft in the use of the stove as a solid fuel stove.

The essential and important features of the present invention reside in the relative arrangement of the gas oven and back whereby to provide an oflset in the angle of which theescape flue may be located to most advantageously position the same for its functions; the arrangement whereby the stove may be readily and quickly convertible for the reception of gas burners or completely closed for the use of solid fuel; the damper control whereby in the use of gaseous fuel a direct outlet is provided and in the fise of a solid fuel flues arranged about the oven through which the products of combustion must find their way to reach the escape flue; and the provision of a damper controlled outlet, which in the use of the article as a gas stove, provides for the escape of fumes from cooking and in the use of the stove as a solid fuel stove operates as a check damper.

Another essential feature consists in providing an extra flue or chamber between the fire pot and oven.

What is claimed is:

1. A combined gas and solid fuel stove including a stove body having a vertical partition terminating below the top of the body to provide a communication between the spaces on opposite sides of the partition, an oven arranged in one space and having its top wall coincident with the height of the partition to provide a flue about the oven,

the connection of the top wall of the oven and the partition breaking the continuity of the flue, an escape flue arranged beyond the body' and disposed above and below the top wall of the oven, the body wall being formed with independent openings to establish communication between said flue above the oven, and the escape flue immediately adjacent and on opposite sides of the top wall of the oven at its juncture with the partition, a canopy rising from the stove body and having a cut out portion, and an oven arranged in such cut out portion and projecting rearwardly of the canopy to form therewith angularly related portions and receive the escape flue. a

2. A combined gas and solid fuel stove including a stove body having an upright back, an oven arranged in a cut out portion of the back and projecting rearwardly of the same to cause one side Wall of the oven to form with the back angularly related meeting surfaces, and an escape flue in communication with the stove body and secured in the angle of such meeting surfaces.

3. A combined gas and solid fuel stove, in-

- cluding a stove body having a vertical partition terminating below the top of the body to provide open communication between the spaces on opposite sides of the partition, a grate arranged in one of said spaces, an oven arranged in the other of said spaces and having its top wall coincident with the height of and connected to the. partition, the top, sides, and bottom of the oven being spaced from the stove body to provide a flue about the oven, the connection of the top wall of the oven and the partition breaking the continuity of the flue, an escapeflue communicating with the flue about the oven immediately adjacent and both above and below the junction of the top wallof the oven and the partition, a damper controlling the communication above the oven wall, the stove body in horizontal alinement with the space above the oven being formed on each side of the partition with openings having closures, and removable gas burners adapted to be inserted through said openings to rest respectively above the grate and above the oven,

whereby the heat products from the fuel in the grate or from the gas burners may be directed about the oven or to the flue independently of the oven.

In testimony whereof I aflix my signature.
